(Cl.199-13) D uring casting of a line of large size types in matrix settingand line casting machines, such as linotype machines, it has beennoticed that the interior of the type slug during casting of large sizetypes is not solidly cast, that is not completely filled with castingmaterial. Such slugs are subjected during printing to premature wear anddo not withstand the high printing pressure they are subjected to, andthe slug is liable to sag in direction transverse to its elongation.These serious disadvantages can only be avoided to a limited extent byvery extensive cooling of the mold in which the slugs are cast. Thesedisadvantages can also not be overcome by increasing the castingpressure, since, due to the diiiiculties of providing a proper sealbetween the mold and the discharge end of the metal pot, as well asbetween the mold and the line of matrices thereon and between theindividual matrices, the casting pressure cannot be increased to adesired extent. To overcome the mentioned disadvantages by means of aslug which has cross sections and dimensions so as to result in a smallheat capacity and corresponding accelerated cooling, is connected withthe disadvantages that the filling out of the depth of the characters,as well as the stability and the resistance against bending duringprinting will be greatly impaired in such a slug.

It is an object of the present invention to overcome these disadvantagesin matrix setting and line casting machines during casting of lines oflarge size types.

It is an additional object of the present invention to provide in amatrix setting and line casting machine an arrangement permitting tocast lines of large size types in a perfect manner.

It is also an object of the present arrangement to provide for suchan'arrangement which can be easily incorporated in a standard matrixsetting and line casting machine.

It is a further object of the present invention to provide for such anarrangement which is composed of relatively few and simple parts so thatthe arrangement can be manufactured at reasonable cost and will stand upperfectly under extended use.

With these objects in view, the present invention mainly comprises in amatrix setting and line casting machine for casting lines of types ofeither large or small size, a mold for casting the line of types,magazine means containing matrices of different size corresponding tocast types of different size adapted to be transferred into castingposition to the mold so that a line of types of desired size may be castin the mold and ejected after casting and means for adjusting the timeperiod between casting and ejection of the line of types in dependenceupon the size of the type cast.

Preferably, the adjusting of the time -period between casting andejection of the line of types, that is the time period during which themolding material injected into the mold is allowed to solidify, iscontrolled from the position of the mold, that is by means of an elementwhich moves the mold between a casting and an ejecting position.Especially suitable for this purpose is a cam disk which is connected bya drive to the turnable mold disk to turn therewith and which, independence on the respective mold section on the mold disk which isbrought during turning of the mold disk into casting position, closes anappropriate switch. An essential advantage of ICC such an arrangement isthat the desired delay between casting and ejection of the line of typesfrom the respective mold section is directly coordinated to that moldsection for which the extended cooling of the mold material is desired.

According to the present invention, it is however, also possible tocontrol the delay between casting and ejection of the line of types independence upon the transfer position of the magazines, that is thedelay is produced when a magazine containing large size matrices is in atransfer position in which the matrices are adapted to be transferred tothe respective mold section of the mold disk so that types ofcorrespondingly large size may be cast therein.

The arrangement for adjusting the time period between casting andejection of the line of types preferably includes an electromagnet orsolenoid which is operatively connected to a coupling forming part oftransmission means between the drive of the matrix setting and linecasting machine and a cam shaft carrying the cams for controlling thevarious elements of the machine. The electromagnet is energized over atime delay relay, which is preferably adjustable, so that the timeperiod in which the drive to the cam shaft is interrupted may beadjusted in a desired manner. Such an arrangement is not only extremelysimple, but has the further advantages that such an arrangement can beeasily incorporated into matrix setting and line casting machines ofstandard construction.

The novel features which are considered as characteristic for theinvention are set forth in particular in the appended claims. Theinvention itself, however, both as to its construction and its method ofoperation, together with additional objects and advantages thereof, willbe 'best understood from the following description of specificembodiments when read in connection with the accompanying drawings, inwhich:

FIG. 1 is a schematic illustration of the arrangement according to thepresent invention;

FIG. la is a schematic illustration of another arrangement according tothe present invention; and

FIG. 2 is an enlarged partly cross sectioned view illustrating thecoupling means and the solenoid cooperating therewith.

Referring now to the drawings, and more speciiically to FIG. l, it willbe seen that the arrangement according to the present invention includesa plurality of superimposed 4magazinesZ respectively containing matricesof different size. The magazines 2 are shift-able in a known manner bymeans of an elevating member or shifting means 1 to bring a selected oneof the magazines 2 in a transfer position in which matrices containedtherein are adapted to be transferred in a known manner, not formingpart of the present invention, to one of the mold sections 40a, 40b 40Cor 40d of a mold disk 40 schematically shown in FIG. 1. One or more cams3 are fixed to the elevating member 1, adapted to cooperate with amicroswitch 4 arranged in fixed position adjacent the elevatingmember 1. The number `of cams 3 and the positioning thereof on theelevating member 1 is such that during movement of .a magazine 2 whichcontains large size matrices to the transfer position, the respectivecam 3 will move the normally open microswitch 4 to its closed position.

A circuit in which connection the casting delay is effected independence on the position of the mold disc can be seen in FIG. 1a. Themold disc 40 carries for each mold which requires time delay contactcams e.g. 3a cooperating with the fixed microswitch 4a. In this examplecontact 3a belongs to the mold 40a. The `cam 3a actuates themicroswit-ch 4a if the mold 40a is in its casting position. In principlethis circuit is analogous 3 tothe circuitshown in FIG. 1 in whichthetime V-delay according to the invention is independent from theposition of the magazines.

The'microswitch 4 forms part of an electric `circuit for energizing anelectromagnet or solenoid 7. The circuit includes further a secondnormally open microswitch 5 `and a time delay -relay 6, which ispreferably adjustable so that upon closing the microswitches`4 and 5 thesolenoid'7 is energized for a time period corresponding the time set inthe time delay relay 6. The solenoid 7, when energized, acts by means ofa lever on a ring 111, slidably guided on .a shaft 17 for movement inaxial direction thereof, and the ring 11 is connected as.

schematically shown in FIG. 1 to la coupling rod 12 slidably guided inan axial bore of the shaft 17 so lthat during energizing of theVsolenoid'7 and movement of the armature thereof in direction of thearrow A, that is `toward'sthe left as viewed in FIG."1, the ring 11 andthe fcoupling rod 12 connected thereto is moved towards .the right, asviewed in FIG. 1, against the actionof a compression spring'13 whichtends to shift the coupling rod -12 towards the'left as viewed inFIG. 1. The right lend lof the coupling rod `12, as viewed in FIG. 1,which Aprojects beyond the shaft 17, is connected by means of.leversto'a pair of friction shoes v14 of Va friction clutch which areadapted to engage an annular inner :face 15 .of a; belt pulley 16 whichVis driven over ia belt drive,

--1 as-l'viewed vin FIG. 2, into the shaft in which a coupling surface15 of the pulley 16 so that the drive from the latter to` the main'kshaft 17 is interrupted.

The shaft 17 carries xedly connected thereto a gear 18 for rotationtherewith, which in turn meshes with a gear 30 fixed to a cam shaft' 31which carries in a known manner a plurality vof cams for controlling the'movements of the various components of the. matrix setting and linecasting machine in a known manner. A cam 32 xedly mounted on the camshaft 31 for rotation therewith has-a pair-of gear segments 32 and 32"successively cooperating with a gearing 33, schematically -shown in FIG.1,` to move la mold section on the turnable mold disk 40, provided witha gear meshing with the gearing 33, in a known manner between a castingposition in which 'casting material is injected'from a melting pot notshown in the drawing into the respective moldsectionin lcastingposition, and an ejecting p0- sition for ejectinng the cast slug fromthe lmold section.

The.cam shaft. carries further'a cam `9 which has 4a cam portion 8adapted 'to cooperate with the microswitch 5 on any other of the camsprovided on the cam shaft,

which are not shown in the drawing, and which cooperate with the otherelements. of thematrix setting and line casting machine in a knownmanner to control the movements of the elements of the machine.Regardless where the cam portion 8 is provided, it has to be arranged insuch a manner that the microswitch 5 is closed whenever an appropriatemold section of the mold disk 40 is in the casting position.

FIG. 2 shows the arrangement of the coupling means `for coupling thepulley 16 to the shaft 17 as well as the arrangement of the solenoid 7vfor disengaging the coupling' means in further detail.

The shaft 17 shown in FIG. 2 is mounted on the frame I u rod 12 isslidably guided, protruding with its right end, as viewed in FIG. 2,beyond the shaft 17. The coupling rod 12 is normally pressed by means ofa 4compression spring 13 which engages with one end thereof a collarxed'to the rod 12 and with the other end thereof a sleeve xed to theright end of the shaft 17 through which the rod 12 extends toward theright, las viewed in FIG. 2, so that a pair of pressure shoes 14 of afriction clutch arrangement .are pressed, by means of the levers 14connected to the right end of the coupling rod 12 in the manner asclearly shown in FIG. 2, against an annular inner face 15 of the pulley16 mountedvfor free rotation on the outer surface of the shaft 17. Thepulley 16 is driven by a belt drive, not shown in the drawing, from amotor of the machine, which mot-or is likewise not shown in the drawing,so that in the position shown in FIG. 2 the shaft 17 is driven from thepulley 16 over the friction clutch 14, 1-5. Fixed to the shaft 17 is apinion 18 which meshes with a gear 30 mounted on thev cam `shaft 31, asshown in FIG. 1, which in turn operates in a known manner the variouscomponents of the matrix setting and "line casting machine by meansofcams and gears mounted thereon. The disengagement ofthe rfriction clutch14, 15 is carried out during normal operation of the machine by means offa ring 11 which is slidably guided on the shaft 13 and which isconnected by a pin 19 screwed at one end into an appropriate bore of thering 11 and extending through a cutout in. the .shaft 17 rand through anappropriate bore in the coupling rod'12. The lever mechanism fornormally moving the ring 11 to the position uncoupling the frictionclutch 14, 15 is not illustrated in FIG. 2, but FIG. 2 illustrates Ionlythe mechanism used to move the ring 11 to the uncoupling position forobtaining a desired delay of movement of the mold disk `from the castingto the ejecting position. This -arrangement includes, as `describedbefore, the solenoid 7, the armature of 'which isv connectedv by meansof .a rod 20 to za two armed lever 10 which is pivoted intermediate itsends at 22 on a projection of a plate 23, which in turn is'xed to themachine frame, as schematically indicated in FIG. 2, and which carriesIalso the solenoid 7- in the manner as shown in FIG. 2.' One yend' ofthe lever 10 is pivotally connected to a fork 21 xed to the rod 20,whereas the lother end of the lever 10 engages one end of a bolt 24slidably guided in a bushing provided on the upper end of the plate 23.'The other end of the bolt 24 carries a ball hearing 25 and the outerrin-g 26 of the ball bearing rollingly engages an abutment face 27 ofthe ring 11.

The operation of the arrangement described -above'will be obvious fromthe above description. If a magazine 2 containing large size matrices isshifted to the transfer position by means of the elevating member 1, thecam 3 located on the elevating member 1 will close the normally openmicroswitch 4. The matrix setting and line casting machine is thenoperated in the normal manner so that a line of matrices istransferredto an appropriate mold section of the mold di'sk40, which mold sectionis brought in a known manner in a casting `po sition in which castinglmaterial isvinjected in a known manner in the appropriate mold section.`The various elements'of the matrix vsetting andA line casting machineare thereby' operated and-controlled from the' cams on the cam shaft 31which is driven from the shaft 17, which in'turn is driven from thepulley 16 when the clutch means 14,':15 are engaged.. The movement ofthe mold disk 40 from lthecasting to the ejecting position in which thecastslug is ejected from the mold is however de layed when large sizematrices are c'ast, since when a magazine 2 containing-larg'esize'matrices is inthe transfer position2 the mioroswitch 4 willbe closed by the cam 3 and the microswitch 5 will al'so'be closed byengagement with the-cam portion 8 when the mold section of the mold disk40 to which the large size matrices have been transferred is in thecasting position so that the solenoid 7 is energized over the time delayrelay `6. Energizing of the solenoid 7 causes movement of the ring 11towards the right, `.as viewed in FIGS. l and 2, to disengage therebythe friction clutch 14, 1S so that the drive from the pulley 16 to theshaft 17 and from the latter to the cam shaft 31 is interrupted and sothat movement of the mold disk 40 from the casting to the ejectionposition is delayed depending on the time to which the time delay 6 isset. This will permit the molding material injected into the respectivemold section containing the large size matrices to properly solidifybefore the mold disk 40 is turned from the casting to the ejectingposition. After expiration of the time set in the time delay relay 6,the latter Iwill break the circuit, thereby de-energizing the solenoid 7so that the friction clutch 14, lwill be re-engaged through the actionof the compression spring 13 and so that the pulley 16 vwill drive theshaft 17 and the latter the cam shaft 31 so that the respective moldsection of the mold disk 40 will be turned from its casting to itsejecting position.

It will be understood that each of the elements described above, or twoor more together, may also find a useful application in other types ofarrangements for adjusting the time period between casting and Vtheejection of a type slug in a matrix setting and line casting machinediffering from the types described xabove.

While the invention has been illustrated and described as embodied in anIarrangement for `adjusting the time period between casting and ejectionof a type slug in a matrix setting and line casting machine independence upon the size of the type cast, it is not intended to belimited to the details shown, since various modifications and structuralchanges may be made without departing in any way from the spirit of thepresent invention.

Without further analysis, the foregoing will so fully reveal the gist ofthe present invention that others can by applying current knowledgereadily adapt it for various -applications without omitting 'featuresthat, from the standpoint of prior art, fairly constitute essentialcharacteristics of the generic or specific aspects of the invention and,therefore, such adaptations should and fare intended to be comprehendedwithin the meaning and range of equivalence of the following claims.
